Patent CA-2282899-A1 (CA)
Title: Adjustable orifice valve
Inventor: HICKEY KURT A
IPC: E21B47/18
Filed: 1999-09-17
Abstract: The invention relates to valves usable downhole and controlled from the surface hydraulically via control lines or by other techniques. The valve has a minimum flow passage which is preferably oriented along its longitudinal axis and a lateral flow passage which opens upon movement of a valve member via applied control pressure from the surface. Alternatively, the valve comprises a tapered needle movable in a throat. When the valve member shifts, additional flow area is exposed to control the backpressure of a fluid by way of hydraulic pressure control from the surface via the control line. The hydraulic control can be with a single control line acting on a piston attached to the valve member with a return spring opposing such movement, or alternatively, can be carried out with a pair of control lines to actuate reverse movements of the valve member. A pressurized gas chamber can be used to act as the closing force opposing applied pressure from the control line for a return of the valve to its minimum flow or maximum throttle position.  Alternatively, an acoustic, electric or other type of surface-directed signal can change the valve position.

Patent CA-2287688-A1 (CA)
Title: Two phase local mobility scheme for wireless access to packet-based networks
Inventor: LA PORTA THOMAS F
IPC: H04L12/56
Filed: 1999-10-28
Abstract: Local mobility within a subnet is supported by classifying wireless base stations, and the routers used to forward packets to those base stations, within defined domains. Domains are defined to incorporate a subnet having a plurality of base stations. Base stations are used by mobile devices to attach to the wired portion of a packet-based network, such as the Internet, and exchange packets thereover with a correspondent node. Packets sent from the correspondent node to the mobile device have a packet destination address corresponding to the mobile device. The mobile device retains this address for the duration of time it is powered up and attached to the Internet via any base station within a given domain. Host-based routing is utilized to update routing table entries corresponding to the mobile device at routers incorporated within a single domain. The routing table entries are established and updated via path setup schemes to convey packets destined for the mobile device along the proper established path through the domain routers and base stations, regardless of the domain base station through which the mobile device is attached. Path setup schemes utilize power up, refresh, and handoff path setup messages to maintain the proper relationship between router interfaces and packet addresses for routing table entries.
Patent CA-2290297-A1 (CA)
Inventor: MCLELLAN LEIGH
IPC: H04L29/06
Filed: 1999-11-23
Abstract: A technique for updating a routing table in a routing device operating over a logical connection in a communication network utilizes a mechanism at a first protocol layer to determine a logical connection status and trigger a routing table update at a second protocol layer based upon the logical connection status. Specifically, the first protocol layer logic monitors the status of the logical channels, and, based on the status of the logical channels, determines the status of the logical connections. When the first protocol layer logic detects a logical channel failure that results in a logical connection failure, the first protocol layer logic triggers a routing table update by sending a signal to the second protocol layer logic indicating that the logical connection failed. Likewise, when the first protocol layer logic determines that communication over the failed logical connection is restored, the first protocol layer logic triggers a routing table update by sending a signal to the second protocol layer logic indicating that the logical connection is restored.

Title: An improved threshold extension block phase estimator for quasi-coherent communications systems
Inventor: OHLSON JOHN
IPC: H04L27/22
Filed: 1998-09-14
Abstract: The invention relates to a threshold extension block phase estimator (TEBPE) which gives improved performance over existing BPE algorithms in the presence of noise. Specifically, the threshold and sector slip performance is superior to that of previously disclosed algorithms. This can be of crucial advantage in coded systems. Another attribute of the TEBPE is that it can be configured as a hybrid feedback loop incorporating characteristics of both the BPE and the PLL. This gives a high degree of flexibility with very fast acquisition times at high signal-to-noise ratio (SNR), and improved threshold performance at low SNR.
